In my previous post “Is it worth upgrading to DSLR? (Part-I)” I wrote about understanding the characteristics, anatomy, Pros and Cons of point-n-shoot camera. In this concluding part I would like to brief out characteristics, anatomy, Pros and Cons of a DSLR. This will help you make a decision to whether or not to upgrade your gear to DSLR.

DSLR Characteristics

DSLR stands for Digital Single Lens Reflex. These cameras can be mounted with a variety of lenses like fish eye, wide angle, telephoto, etc. Such a variety of interchangeable lenses provides you with a greater creative control over ability to select lenses based on virtually any photographic situation.

The other major design difference between DSLR and point-and-shoot cameras is that most DSLRs only provide a “through-the-lens” optical viewfinder, although some models such as select Sony α (alpha) DSLRs feature the ability to compose and see a live preview of your shots on the camera’s LCD monitor. For DSLRs that don’t include this feature, you frame the shot by holding the viewfinder up to your eye.

Point-n-Shoot Anatomy

1. Light rays pass through the lens and strike a mirror.
2. The mirror reflects the light up to a focusing screen
3. Light rays then enter a block of glass called a pentaprism where they are reflected to produce an image which can be seen in the viewfinder.
4. When you press the shutter release button, the mirror flips up and shutter opens up which exposes the image to image sensor.

DSLR Pros

• Image Quality- These cameras usually have bigger image sensors as compared to compact point-n-shoot cameras. For a 8-10 Megapixel point-n-shoot the size of image sensor is approximately 8.5 x 6.5 mm and a startup DSLR with same Megapixels will have an image sensor approximately 23 x 15 mm. As I said larger image sensor translates directly to better image quality in terms of fineness, color depth, detail and dynamic range.

• Full Control- Unlike point-n-shoot cameras, DSLRs offers a huge list of customizable options. You can manually set your own fully or partial combination of shutter speed and aperture, white balance, contrast, metering, auto/manual focus, depth of field, ISO, etc. Along with these manual setting today’s DSLRS also offer dial mode feature where you can handle your camera just like a point-n-shoot. Just turn the dial to available shooting modes and click the shutter release button.

• No Shutter Lag- DSLRs have virtually no delay between the time that you click the shutter and the image is taken due to the fact that they focus at a very great speed. You can continuously press shutter release button to get a burst of images without waiting in-between. I guarantee, you will never miss an important shot due to shutter lag.

• Instant Startup- Now-a-days DSLRs have instant startup times. This makes a lot sense when you see a fast flying UFO and your camera is in OFF mode, you quickly grab your camera start it and capture the unbelievable moments. With a point-n-shoot camera this seems to be a dream because it will take a couple of seconds to warm up and then focus for another second making your UFO invisible into the skies

• Minimal Noise- Due to large image sensors in these cameras the setting of 100 ISO will produce less noisy image as compared with same setting in a point-n-shoot.

• You get what you see- Unlike point-n-shoot cameras, you get the same image in the viewfinder what your image sensor see.

• Higher ISO Range- DSLRs normally beat the ISO range in point-n-shoot. They may rage from 100-3200+ ISO these days. I’ve explained ISO in detail with an illustration in one of my posts during the month of May 2009.

• Depth-of-Field- I love this concept. Just blur out the objects you don’t want in your scene. Using a combination of Shutter and aperture setting you can set your own depth of field. Stay on for my post on this concept soon.

• A Lens for every occasion- Once bought a DSLR you don’t get stuck with single fixed lens because you can upgrade your lenses with shooting conditions like capturing close up of that little honey bee on a sunflower or capturing your baby’s naughty little acts or looking directly into the eyes of a ferocious lion or capturing that beautiful eagle taking its flight. These cameras can be mounted with a great variety of lenses ranging from super wide angle to Telephoto lenses. Wait for my post that I am planning to write soon on lenses.

• Adaptability- Once bought a DSLR let me assure you won’t have to upgrade to a new camera that often because DSLR models do not get updated quite as often as point and shoot models. You will only upgrade your lenses that to depends upon your shooting requirements.

• External Flash- With DSLRs you get an option to have an external flash unit which gives you a bigger are to cover with illumination. You even have an option to have multiple remote slave flash units with your camera which gives you more illumination. Wait for my post on understanding flash, where I am planning to cover all kinds of basic to advance flash operation to attain pro like quality of pictures.

DSLR Cons

• Weight- DSLRs are basically lot heavier and bulkier than point-n-shoot. Planning for an outing with your DSLR will add up another piece of a backpack to your luggage. My own DSLR with 18-105 mm lens kit build up a load of 5 Lbs. I can easily slide my point-n-shoot in my jeans pocket.

• Price- Even though DSLRs are becoming more and more affordable, you can still get a low-end point-n-shoot camera for much less money. Once bought a DSLR body you will surely have to have a lens kit, a couple of filters, tripod, monopod, external flash unit, reflectors, macro lenses, etc. We are actually talking about a collection of four figures USD.

• Sheer learning curve- Buying a DSLR simply can’t make you a good photographer, you will have to learn and practice a lot. Before and after buying a DSLR you will have to do a lot of study and practice to attain a professional ‘WOW’ picture. If you plan to own a DSLR study and practice the concepts like ISO, Exposure, White Balance, Metering, Aperture, Shutter Speed, and a lot more. If you don’t want to go deeper into the technical aspects and planning only using full time auto mode, my suggestion to you is stick with your point-n-shoot.

• Maintenance- For my point-n-shoot I never ever have to care about the dust going into the camera body. Although I often clean the front fixed lens with a soft cloth but that is not a geek’s business. In case of DSLR you have a variety of lenses that you mount and un mount based on shooting conditions. Every time you mount-un mount you expose your DSLRs’ expensive image sensor and reflex optics to dust. Dust on an image sensor can result in blemished mages and cleaning out the dust is no layman’s job. A small mistake can cost you a loss of your camera optics.

• That creepy motor noise- Since DSLRs are bigger in size they have bigger optics and to control those optics they have motors inbuilt. Every time you auto focus you will hear a noise from lens’s motor. For some this might be a point of consideration.

• Live View- In many DSLRs the only way to frame your scene is with an optical viewfinder. Although now-a-days you can see a couple of manufacturers that provide Live View LCD but taking pictures using a live view is never a perfect idea.

Now that I’ve brief out the pros and cons of DSLRs and Point-n-Shoot Cameras, I leave you to make your best decision to upgrade or not. In my next post I’ll post a very important entry, which will help you choosing a good DSLR Camera.

Hope you enjoyed this post of mine.
